Brake Light Wires

[WhiteLimited]

When you take your tail light out there are 3 wires that go into the back of the bulb. What does what Ground Running and Brake. There is a Green and 2 Black. I am putting my LED tail lights back in and this is the only thing holding me back on his beautiful 65f day out side I know witch wire is witch for the turn signals. Thanks Cheers!

Get a test light, attach a ground to the light and put on your lights in the truck, probe away with lights on and it will answer everything....

You turn on your lights and put your turn signal on and attach the clip to a body metal part that will ground and touch to pick end on the test light to the three wires. One will be on all the time, one will blink and oen will do nothing,ground wire.
